Chatter from build plate

See the video.  The build plate chatters when printing.  If I very lightly place my finger on it to dampen the vibrations, the sound goes away.  It doesn't take much weight to do this, the Sun Gear Installation Tool placed on the corner of the build plate also works.  I have tried two different build plates with the same results.  I checked the screws attaching the heat bed for proper tightness, and that did not change anything.  

The touch on the build plate to dampen the vibrations is so slight.  As best I can tell, I'm not moving it, but rather dampening the vibrations.

Help.

SOLVED!

As it turned out, the center spacer between the Heat Bed and the Y-axis plate wasn't quite right.  Instead of the machine screw going through the hole in the spacer, the spacer was sitting next to the hole in the Y-axis plate and pinched by the machine screw.  Whew!
